摘要
在数学中经常要用到复变函数在极点邻域内展开的罗朗级数。本文推出了用导数运算计算该罗朗系数的公式 ,并举出应用实例。
It is widely used to develop complex functions into Laurent series at the neighborhood of a pole.This paper deduces the formulae to obtain the coefficients of the Laurent series through differential calculation.Some typical examples are presented for illustration.
